Description
mixed min ( array $values )
mixed min ( mixed $value1 , mixed $value2 [, mixed $value3... ] )

If the first and only parameter is an array, min() returns the lowest value in that array. If at least two parameters are provided, min() returns the smallest of these values. 

Note: PHP will evaluate a non-numeric string as 0 if compared to integer, but still return the string if it's seen as the numerically lowest value. If multiple arguments evaluate to 0, min() will return the lowest alphanumerical string value if any strings are given, else a numeric 0 is returned.

Parameters
An array containing the values.

Return Values
min() returns the numerically lowest of the parameter values.
